Hi. I never had this problem. I'm on 4.1.2 xwlsd. What i did was a clean install of my system. This instructions are for the international version GT-I9100.

1. Download Odin3 v1.87.

2. Get the official firmware form sammobile.com.

3. Open Odin3 and put your phone in download mode. Connect it to the PC and make sure the yellow square appears.

4. I used a pit file to reparation but don't recommend you try it. You can hard brick your phone.

5. Thick auto reboot, F. Reset time, phone EFS clear, phone bootloader update.

6. Press on PDA and browse the firmware you downloaded. Be sure to extract it first if it's a .zip file. You should see a .tar file.

Now you have a clean install of original firmware. Good luck.

Samsung Electro Mechanics for me too. It's not a HW issue, because under stock ICS, or under AOSP/CM/AOKP JB the wifi works fine. The issue exists only with the recent stock JB roms, and those based on them (NeatROM, Omega, WanamLite, etc). It's also not caused by the kernel, because I've tried stock-based kernels and upstream-based kernels (Dorimanx, Siyah) and the issue persisted.

Has anyone tried flashing older baseband/modems? They shouldn't be related to the wifi in theory, but who knows...

Same Problem

I have updated my Australian Vodafone (unlocked) now on TPG who use Optus.

4.1.2

i9100XXLS8

1. It wanted the network pin on start which I don't have.

booted in update mode: installed Root_SuperSU.0.98-Busybox.1.20.2-signed.zip

Once rooted could run: GalaxSimUnlock.apk

2. WiFi wouldn't connect: Failed message as soon as I entered password.

I have my password saved on my phone in a .txt file as it is loooong and complicated.

I copy and paste it.

Soon as I logged into my router and turned off password it connected perfectly and ran at full speed.

I need to investigate this as I am not leaving my WiFi open.

3. I am am only getting G connection for data ? 38kbps ?

May need to look at a different modem ?

Router is using WPA2-PSK (AES) security.

To achieve the best performance with 11N wireless adapters under robust security network, NETGEAR recommends that you change your network's security option to WPA2-PSK.

---------- Post added at 07:15 PM ---------- Previous post was at 06:55 PM ----------

tested something.

Copying and pasting your password doesn't work with that Polaris office or whatever default crap it opens in.

I double checked my password by opening the .txt file my phone and copying and pasting it into the text file I have stored on my PC.

edd02fbf9932484785a69d1266d8c7c873f08b4a228c10746677f971591b6c3

edd02fbf9932484785a69d1266d8c7c873f08b4a228c10746677f971591b6c3

It looks the same when you tick view password on the phone once pasted but it doesn't work.

Once I bit the bullet and typed in that manually it connected first try.

by the way what wireless routers you guys have? I have old buffalo wbr2-g54 around 2005 or something. Maybe it could be related to routers? I am using that kind of encryption (wpa2-psk aes) which is mentioned in last post if I remember it correct.
[Galaxy S II Q&A, Help & Troubleshooting] BAZZI_US:
Any news? I ran into the same problem with two S2 devices. Both now on XWLSD / DBT. All wifis reconnects with 0.5 Mbit/s real data rate, after reentering the wifi signal, e.g. coming home. Restarting wifi on the S2 solves it immediately... until the next reconnect.
[Galaxy S II Q&A, Help & Troubleshooting] ne00en:
Nothing new. I don't know what is so different between 4.04 and 4.1.2 stock rom. I have same router, so it can't be router fault.
[Galaxy S II Q&A, Help & Troubleshooting] BAZZI_US:
It is definitely not a router issue. I have two S2 which are connected to several routers over some days. Allways the same problem with each router and each phone.

I will try to reflash with odin, but without a reset. I updated with KIES (what I usually do not do) just to see, if it's still a bad idea. ^^

UPDATE:

I flashed via Odin. I'm not sure if the problem is solved. But I found out, that the connection speed of WiFi changes. If I leave the device for a minute without any data traffic, the speed is reduced to 26 Mbit/s or even lower. If I run a speed test, I get the corresponding slow speed, which are then real 1 Mbit/s or less. But after that speed test, the connection speed increases to 39 Mbit/s or higher.

The connection speed ist changing in a very broad range. I got until now everything from 6 to 65 Mbit/s within five minutes. I'm sitting 2 m next to the Wifi router, so don't tell me, there's any interference! ^^
[Galaxy S II Q&A, Help & Troubleshooting] RandomPlayer:
so samsung has screwed up something if this problem doesn't bother other jb devices. Let's just hope that samsung fixes wlan bug before it ends s2 device support.
[Galaxy S II Q&A, Help & Troubleshooting] BAZZI_US:
Yes, that's what I'm afraid of. My experience with bug fixes by Samsung would lead me to the assumption, that it'll be fixed with v4.2. And this is rather unlikely to happen. ^^
[Galaxy S II Q&A, Help & Troubleshooting] BAZZI_US:
I found a solution, which worked for me. Well, it even worked for two independent wifi routers and S2s. The following text refers to each of both (independent) networks.

Usually I configured the router to always use the same channel, because some devices do not recognize an automatic channel change by the router immediately and the connection breaks for a few seconds.

I analysed the surrounding wifi networks with an app (Wifi Analyzer by Kevin Yuan) and decided to use the least "packed" channel for my network. That has been working fine for a long time with all devices.

Now, since Jelly Bean the S2 keeps decreasing the connection speed to 5 Mbit/s, which is stable, but of course very slow. I analysed the surrounding networks again. I found, that my channel has got some users over the time. So I searched again for a less occupied channel and reconfigured the wifi router.

And guess what! I now have a link speed of 65 Mbit/s or sometimes 54 Mbit/s (I recommend Network Signal Info by KAIBITS Software). Speedtests show, that this speed is actaully used.

As I already mentioned, I did this procedure on both networks successfully. I don't know why this behaviour occurs just since the Jelly Bean update. Perhaps there is a new way how Jelly Bean ensures a stable wifi connection, which has a higher priority in stability than in speed. I don't know. But "he who heals is right". :)

Give it a try!

4.1.2 XWLSN

A couple of days ago,a new stock rom was released...its name is XWLSN. It is an European rom for the Noth Europe countries. Somewhere I read it contains a lot of minor bug fixes, and in some Android sites I read XWLSN is raccomended for all the Galaxy S2 that are affected by the wifi stability issue.

Actually I downgraded my S2 to ICS(no wifi problem with 4.0.3),and I don't want to try XWLSN, bacause I'm really bored due to all the proofs I did the last mounth. So...maybe someone of you will try XWLSN rom. In this case,could you inform us if Samsung fixes the problem we have with the wifi stability?

[Galaxy S II Q&A, Help & Troubleshooting] warezxts:
LSN based wifi issue

A little history:

i follow the NeatROMs, from version based stable LS8, and in every rom whis is after the leaked LSJ, same error happened.

I googled it, and found the link mentioned in post#1 of this thread, and i just replaced the wifi driver manually all the time (XXX to LSJ)

BTW it was not repaired in the base rom either.

Now i am at the very hyped LSN based rom, and i tried the same exchange, but this time it didnt worked. Its even not switch on after change.

With LSD and MS1 the method worked.

---------- Post added at 11:04 AM ---------- Previous post was at 10:59 AM ----------

i read different speculations about the error.

I can confirm, its all about the Wifi Driver.

i used at home, work (LEAP), different places, different roms, different kernels, different programs, different routers.

So we can close out these, its all about the wifi driver as i mentioned.

I will follow this topic, may we try to figure out something, i need leap to use wifi.

untill that i replace my backup to MS1 rom

i go home and try to save out AOSP drivers from rom base, and i will write the result.
[Galaxy S II Q&A, Help & Troubleshooting] warezxts:
i started to give it up...

i replaced with wifi AOKP - didnt turn on, AOSP - didnt turn on, back to my original wifi driver from the rom zip, and guess what happened?

yes, didnt turn on. :(

i think i replace my oldel rom, and when there will be a solution i will let you know guys!
[Galaxy S II Q&A, Help & Troubleshooting] warezxts:
My solution

A possible solution:

The old driver is working but needs the exact rights.

turn off wifi

1. rename etc/wifi folder to wifi2

2. copy the wifi folder from LSJ (attached)

3. go to the etc folder, and set permissions

It must be like set and looks like on the attached pictures.

restart not needed just turn wifi on. LEAP MUST WORK!
[Galaxy S II Q&A, Help & Troubleshooting] hops77:
Warezxts, i don't think you have the same problem we have... Our issue is related to the wifi connection instability... When our s2 state changes to sleep mode, wifi connection stops working until we switch the wifi toggle off and on again.

Hey guys !

I found a solution for this wifi bug (not that effective, but still you can give it a try)..it doesn't involve any tweaks or any such thing.

Download this app named "Wifi High Performance", free of course :

Enable it and bamm ! Wifi would remain on and active all time :D

If it didn't work, download ttorrent from play store, open it and let it run in the background.

Wifi would be working fully as it will not allow to let wifi go to sleep (which is the bug) :D

This may be specific to my config... I uninstalled CallRecorder (Skvalex version 1.36, was also running prior beta versions), rebooted, and that seems to have taken care of it for me. I just downloaded about 600MB of data on WIFI without interruption.

But, I still have the bug where the "Keep Wi-Fi on during sleep" setting reverts back to "Always" all by itself. I suspect that something we have installed (probably with root permission) is messing with one of the settings files/databases at the wrong time.
[Galaxy S II Q&A, Help & Troubleshooting] BAZZI_US:
It's not root depending. It's also not an app which causes wifi speed to drop.

This happens with a clean installed system with no user apps installed yet.

And again: The problem is, that wife speed drops to nearly zero after some time until wifi is restarted on the Galaxy. There is no disconnect or wifi driver crash. Just the speed decreases to a few kilobits per second.
